Plantetary power shift with 432 mm / 17" diameter, high-torque-capacity oil clutches. Special modulation system permits smooth speed changes under load.

Single-stage torque converter with output torque divider. Connected to transmission by double universal joint for unit construction to provide service ease.

 Hydraulically released, spring-applied, multiple-disc clutches and brakes are cooled by pressurized oil and require no adjustment. Each assembly serviceable as a unit.

Separate hand controlled steering clutches and pedal controlled braking provide precise steering control.

 Sealed and Lubricated track

Sealed and lubricated track surrounds the track pin with lubricant to virtually eliminate internal pin and bushing wear as a maintenance consideration. Positive pin retention locks the pin to the link to prevent "end play" or "pin walking". Hydraulic track adjusters, track guiding guards and two piece master link standard. Features large pins, bushings and bolts with positive pin retention which leads to long track seal life.

 Two levers control all functions including raise, lower, quick drop and power down, high and low range and speed adjustments. Left hand lever controls hook, right hand lever controls the boom. Arm rests support arms for operator comfort.

Hydraulically driven drawworks give infinite line speed control.
